One important thing with her mod is that she has a backwards facing tile now. This means fun times for Python fans, Nagant users, or users of any doll who prefers to be in the middle of the back row and could benefit from an attack speed buff, which happens a lot of the time. She also debuffs the enemy if the node you're fighting on is controlled by you, and buffs your attack and move speed if it isn't, but those are kind of icing on the cake for an already useful doll.

Oh, and the move speed buff is hilarious when combined with other move speed buffs, turning Hanyang Mod into a a rocket. This makes some boss fights hilariously easy as you give no fucks about their mechanics, and 60s is long enough for most battles.

You can probably leave her at Mod2, but her Mod3 equip is a suppressor equivalent with +20 evade at max. It's up to you whether that's worth it or not.

"Yay, we can all clear singularity now!" Oh wait... :V Fucking Ceia, I swear...

Yeah, she's a little over-hyped, but she's actually a fairly solid unit. A stacking buff every few seconds? Not bad at all. This allows her to buff firepower, accuracy and rate of fire all at once. Her main issue is it takes a few seconds for her skills to REALLY kick in, but she's great for the longer fights that start creeping up here and there, and for things like backing up M4 in her railgun mode. Not super necessary compared to before now that we have lots of buffing HGs, but she's handy for things like ranking maps.

Another fun thing about this mod you might not know is that the passive 2nd skill automatically activates on a cooldown that you can't see, so rifle tile buffs (which speed up handgun cooldowns) make this activate faster.

Her Mod 3 equipment is kinda pointless for her role, though, so unless you like the art or have bad OCD, she's fine at Mod 2.
